best size of container for flowering

well just transplanted my plants from a couple coffee containers to 2.5-3 gallon containers there about 9 inchs tall of leafs then have about 4 inchs of stock buried, was wondering as im switching to flower in 2 weeks what size i will need to transplant to? there a month old now so and growing under cfl lights

how many you've got? i prefer only one transfer, so i would think to stay flowering on thos 3 gal pots. on what light you gonna flower?

got 2 plants, was just gonna use some cfl in the 2700-3k range

depending how long ur going to keep vegging for.. but honestly alot of people transplant.. give the plants a week or 2 .... to toss the roots into the new pot.. and then tos into flower with great results.. i just realized that CANNA COCO allows for a bigger root system in a smaller pot.. so u can SOG in 1 gallon grow bags.. and have plants that look like they were grown in 2-3 galons of soil

if you transplant right before flower you don't usually need to transplant again...although I transplanted one plant into a 3 gallon and then flowered and when it was 5 weeks in I had to transplant it again...so now if I have trained the plant to be bigger, I go ahead and transplant into a much larger pot before flower...like from a solo cup to a 7 gallon...unless I plan to just flower it without extra veg and training...then I will use a 3 gallon...
